Representing IP addresses in XML Schema

How about this...

( (1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5]).){3}(1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])

I took a quick look at the new version of the spec, and this seems to conform
to the syntax.  This will not check for IP addresses in the 127.?.?.? rang or
the 0.?.?.? range, but that could be added.
